1. ADM3078EYRZ-REEL7 Substitution Conclusion
The ADM3078EYRZ-REEL7 can serve as a conditional replacement, with two key differences requiring attention: its data rate (16 Mbps) is lower than the original part (20 Mbps), which may fail to meet the original design requirements in high-speed communication scenarios; meanwhile, its receiver hysteresis (100 mV) is significantly higher than the original (25 mV). While this improves noise immunity, it may reduce sensitivity in low‑level signal environments. If the actual application operates at ≤16 Mbps and the system is exposed to substantial noise, this device is pin‑ and supply‑compatible. However, if the original design relies on the 20 Mbps rate or low‑hysteresis characteristics, substitution could lead to performance degradation or communication failure.
2. ADM3078EARZ Substitution Conclusion
The substitution conclusion for the ADM3078EARZ is identical to that of the ADM3078EYRZ-REEL7, as both share the same core parameters (including 16 Mbps data rate, 100 mV hysteresis, etc.). This variant likewise differs from the original part in speed and hysteresis characteristics: the reduced data rate may limit high‑speed applications, while the higher hysteresis improves noise rejection but can impair small‑signal detection. It can be substituted in applications where the required data rate is ≤16 Mbps and strong noise immunity is needed. However, if the original system operates at the full 20 Mbps or depends on low‑hysteresis thresholds, substitution is not viable.
